I need to add disk space to a Dell PowerEdge 1600SC. The RAID controller is an LSI Logic 1030 Ultra 320 (SCSI). Currently there are two disks in a RAID 1 (mirror) configuration. I would like to keep the current data and expand the volume with more disks. Seems pretty straight forward, but after browsing the user manual, I am hesitant about this as it says to erase the data on the primary disk when configuring a disk array of more than two disks? Has anyone performed this operation on this piece of hardware or something similar successfully?
